Very simple question 2

Shell Programming and Scripting

Hey , another question is below:

Administrator@fe038390aa60482 ~/Frank/20130509
$ c=`ls -ls`

Administrator@fe038390aa60482 ~/Frank/20130509
$ echo $c
Total 4 1 -rwxr--r-- 1 Administrator None 482 May 9 11:07 do_increment 1 -rwxr
--r-- 1 Administrator None 272 May 9 11:32 do_square 1 -rwxr-xr-x 1 Administrator None 273 May  9 10:40 do_square.bak 1 -rwxr--r-- 1 Administrator None 136 May  9 11:38 myfunction

why the newlines are removed just because I assign the command "ls -ls" to a variable c and echo the value of c ?
what if I want to display them normally as follows by using command substitution like above:

Administrator@fe038390aa60482 ~/Frank/20130509
$ ls -ls
Total 4
1 -rwxr--r-- 1 Administrator None 482 May  9 11:07 do_increment
1 -rwxr--r-- 1 Administrator None 272 May 9 11:32 do_square
1 -rwxr-xr-x 1 Administrator None 273 May 9 10:40 do_square.bak
1 -rwxr--r-- 1 Administrator None 136 May 9 11:38 myfunction

Hi franksunn,
The newlines are not preserved in the echo output,
You need to use printf to get the formatting correct , check this out ..

printf "$c \n"
